. bottoms to facilitate the dumping of the contents. v

Such cars at the present time are so constructed as to have bot-tomswhich are capable of a swinging movement, but this movement, because ofthe particular construction and due to-the given height-of the bottomsfrom the ground, is limited, so that the discharge opening formed issmall. Hence the contents can only slowly befdischarged and when thepieces of coal, ore, or the like, are frozen together or for some otherreason stick together, pounding and pushing are required to cause orhasten-the discharge. l

The principal object of my invention is to provide a constructionwhereby these drawbacks will be obviated.

With this and other objects in view, my invention consists in the novelconstruction, combination and arrangement of parts as will be.hereinafter more fully described and defined in the appended claims.

In the accompanying drawing in which similar reference characters denotecorresponding parts, Fig. l is a side elevation; Fig. 2 a top plan view;Fig. 3 a bottom plan view as seen along line 33 of Fig. 1; Fig. 4 is anenlarged cross section on line 4L-4 of Fig. 2 and Fig] 5 is an enlargedcross section on line 5--5 of Fig. 2.

The car, as usual, is composed of a rectangular wheel base frame 10,walls 11, which at their lower ends are obliquely-cut away andareadapted to support. chutes 12 carried by the end walls (not shown). The

"' base frame 10 through centrally longitudinally extending bars 10 andcross bars 10 is divided into a number of sections, four in the presentexample, each section having a separate and independently movable bottom13. There are two longitudinal bars 10' separating these sectionslaterally. These bars are parallel to one another and are spacedsufficiently far apart to accommodate between themselves in parallelarrangement,

longitudinally extending spindles 14, two on each side of the centralcross bars 10 The central cross bags 10 are also spaced apart to'accommodate between themselves cross spindles 15, two on each side ofthe longitudinal line of the car. The longitudinal spindles 14 aresupported in bearings 16 and 17 and intermediate bearings 18 and areformed each with two or more hook shaped members 19 adapted to engagethe inner free edges of the movable bottoms 13. The oppositelongitudinal edge of each bottom is formed with two or more upwardlyprojecting angular and bifurcated arms 20 formed with cross pivots 21.Projecting from the frame 1 10 upwardly are longitudinally groovedsupports 22 adapted to rotatively engage said cross pivots 21, so thatwhen the bottom 13 is swung downwardly on its pivot 21 it will, byreason of the elevated supporting points be permitted to swing clear ofthe tracks and the ground; and open to'its full extent, so that thecontents can be completely dumped at once.

.The longitudinal spindles 14 are free to rotate in their bearings 16,17 and 18, but means are provided to hold the same against rotation andthe hooks 19 in engagement with the inner edges of the bottoms 13. Thesemeans comprise looped arms 23 preferably made of wire'or the like andpivotally connected to arms 24 projecting from the spindles 14 andstationary fingeis 25, projecting from the frame 10 serving to engagethe loops 23 of said arms. Foldable look pins 26 fitting in holes 25 ofthe fingers 25 may serve to prevent the loops 23 from slipping off thefingers.

When the contents are to be dumped the looped arms are disengagedfromthe fingers 25 after the withdrawal of the lock pins, whereby thespindle 14 will be rotated and the locking member 19 released,permitting the bottom to swing downwardly under the load.

For the return of thebottoms into closed position, I employ thefollowing contrivance:

The spindles 15 carry ratchet wheels 27 with which cooperate pawls 28fulcrumed on the brackets or bearings 29 of the spindles. Fastened toand adapted to wind around these spindles are cables, ropes or the like30, which are hooked to or otherwise attached to the bottoms as at 31.When the bottoms are in closed position. the cables lltl hll

(fil

are wound around the spindles, and the latter locked against rotation bythe engagement of the pawls with the ratchet wheels. The outer ends ofthe spindles are formed to squares 15' for the application of crankswhereby the spindles can be..turned to raise the bottoms into closedposition.

In order to prevent the material from falling into the spaces occupiedby the spindles and obstructing the operation thereof, said spaces onthe inside of the car are covered by hoods 32, 33 which are suitablyfixed in position and the outer or upper faces of which may be made roofshaped, as shown, to act as chutes, so that when the material is dumpedthe pieces lying on the hoods will have the tendency to slide down andpass through the opened bottoms. The simplicity whereby the bottoms canbe released and the arrangement of the hinges of the bottoms at acertain elevation in order that the bottoms when swung open will notstrike the ground, are advantages rendering my construction verypracticable. 'lhe grooves 22 of the supports 22 are open at their upperends to permit the passage of the cross pins 21 into said grooves.Locking pins 3d may be used to secure the pivots in said grooves.

From the inside of the car the hinges of the bottoms are shielded bycasings or hoods 35 having inwardly slanting tops 35.

What I claim is l. A car for coal or the like, having a laterallyswinging sectional bottom whose fulcrunis are arranged at anelevationabove the base frame, freely rotatable spindles formed withmeans engaging said bottomin closed position and means operativelyconnected to said spindles and adapted to bedetachably connected tostationary parts of the car for locking said rotatable spindles inoperative position.

2. A. car for coal or the like, having a laterally swinging sectionalbottom whose fulcrums are arranged at an elevation above the base frame,a freely rotatable spindle formed with means engaging the said bottomin. closed position, and an arm pivotally connected to said spindle andcapable of engaging a stationary part to lock said spindle in operativeposition.

3. in a car for coal or the like, a base frame having a plurality oflaterally swin ing bottoms, each bottom being pivotally suspended at anelevation from said base frame, rotatable spindles arranged betweenadjoining bottoms and having means engaging the said bottoms in closedposition, and arms on said spindles adapted to bedetachtaiarea ablyconnected to stationary parts of the car to hold said spindlesinoperative posie tlon.

4C. In a car for coal or the like, an open base frame dividedlongitudinally and transversely into a number of sections, bottoms forsaid sections, each bottom being formed with upwardly projectingbifurcated arms carrying cross pins, upwardly projecting groovedsupports on said base frame to rotatively bear said pins and formtherewith hinges at an elevation from said base frame, freely rotatablemembers to engage said bottoms in closed position and means for holdingsaid members in operative position.

5. In a car for coal or the like, an open base frame, dividedlongitudinally and transversely into several sections, swinging bottomsfor said sections, rotatable spindles extending between the lateralsections and having means for engaging said bottoms in closed position,arms on said spindles adapt ed to be detachably connected to stationaryparts of the car for locking said spindles in operative position andhoods inside the car to shield said spindles.

6. ln a car for coal or the like, an open base frame, a laterallyswinging sectional bottom, rotatable hooks for engaging said bottom inclosed position, an arm operatively connected to said hooks and adaptedto be detachably connected to a stationary part of the car for lockingsaid first hooks in operative position and a pawl and ratchet controlledspindle connected to said bottom and serving to raise said bottom intoclosed pos1- tion. I

7. In a car for coal or the like, an open base frame dividedlongitudinally and transversely into several sections, laterally andindependently swinging bottoms for said sections, longitudinal spindlesbetween the adjoining longitudinal edges of said sections, means on saidspindles to engage said bottoms in closed position, arms on saidspindles adapted to be detachably connected to stationary parts of thecar for holding said. longitudinal spindles in operative position.manually operable cross spindles between the adjoining inner end edgesof said sec tions, said cross spindles being connected to said bottomsto close said bottoms and hoods inside the car to shield saidlongitudinal and cross spindles.
